ABSTRACT:
A gas-sealing device for a web passage section through the wall of a treatment chamber which enables effective sealing to be achieved not only in a small space but also with a small volume of gas, thereby contributing to a reduction of both equipment and operating costs. First and second gas jetting devices facing opposite sides of a web at the wall of the treatment chamber. Each of the first and second gas jetting devices includes a first slot for jetting a pressurized inert gas toward the treatment chamber, a second slot for jetting a gas containing a low-content gas, the second slot being on the treatment-chamber side of the first slot, and a third slot for sucking air and other gases, the third slot being on the outside side of the first slot.
